Electricity Saving Tips For Homes And Offices

Split or Window … which air conditioner should you buy?

By on August 26, 2015

Hindi Translation: स्प्लिट और विंडो - कौन सा एयर कंडीशनर खरीदना चाहिए?

Should I buy a split air conditioner or a window air conditioner? This is a question that many air conditioner buyers thinks of, before making a purchase. And we keep getting this question quite regularly at Bijli Bachao. It is not just about split or window, but about a whole lot of things that should be considered while buying an air conditioner.  Air Conditioner is an appliance that can significantly blow up your electricity bills and utmost care should be taken while buying one. With this article we would try to provide you some guidelines on things to take care of before making a purchase decision for an air conditioner. Please note an air conditioner bought once will go on for next 10 years at least and thus it is important to make a right decision.

Air Conditioner

Split vs Window

Buying a split or a window is something that worries a lot of people. But from energy efficiency perspective there is no preferred choice. Both split and window can be equally efficient. What matters is EER or Energy Efficiency Ratio of the air conditioner. EER represents the amount of cooling an air conditioner can provide per watt of electricity it consumes. Bureau of Energy Efficiency rates air conditioners on its star rating based on EER of air conditioners. Higher the EER of air conditioner higher the star rating it will have. So a 5 star rated air conditioner provides more cooling per watt of electricity used.

Both split and window can have high EER ratios. But it is observed that Split air conditioners have more number of models in BEE 5 star rating as compared to Window air conditioners (check our research on air conditioners at this link: link). So if you are looking for high efficiency air conditioners then split air conditioners can provide you more options.

The main difference between the two is that window air conditioner has a single unit whereas split air conditioner has 2 units (indoor and outdoor). Split is lot more silent in operation as compared to window and looks aesthetically pleasing, but is relatively more complicated to install and requires more space as compared to window air conditioner.

Right sizing an air conditioner is very important

The most important thing that one should figure out before buying any air conditioner is the right size of the air conditioner. This can significantly impact your electricity bills. And from size we mean tonnage of air conditioner. Every room that is cooled has a certain amount of heat that depends on:

  1. Size of the room. This determines the amount of air in the room that needs to be cooled.
  2. Number of people in the room. Every human being emits heat and air conditioner needs to cool it.
  3. Amount of stuff kept in the room. Please note every item kept in the room will get cooled from the air conditioner, so lesser the stuff, lesser the electricity air conditioner will consume.
  4. Number of electrical appliances in the room (most electrical appliances emit heat, especially lights). Incandescent light bulbs can increase cooling load.
  5. Windows in the room. More the windows, more is the heat coming from outside. Well-insulated windows reduce cooling load. Check our insulation section for more details: https://www.bijlibachao.com/Save-Electricity/Insulation/
  6. Walls facing the sun can increase cooling load. Touch your walls and windows to check if they are hot or not and using the tips in insulation section to prevent heating of the room.

The amount of heat in a room and that coming in from walls and windows is represented in BTU (or British Thermal Unit). BTU is sum of heat from all the above-mentioned sources.

Every air conditioner has a cooling capacity, which is represented in BTU/hr. It is the BTUs of heat that it can remove in an hour. If the heat coming in the room (in BTUs) is more than the heat that air conditioner can remove, then the air conditioner will not be as effective. Thus an undersized air conditioner cannot remove heat effectively and the compressor of the air conditioner will continue running all the time thereby consuming more electricity.

With an undersized air conditioner, the compressor will keep running all the time and the temperature will not reach the desired level. They will not only be ineffective in cooling, but will also consume more electricity.

An oversized air conditioner will not only over cool your room but also will be ineffective in removing the humidity in a room. So if you set AC to 25, the extra energy that the compressor provides will cool it beyond 25. It will have shorter run cycles but all air conditioners are designed for optimum run cycles and if the cycle is shorter than that then the efficiency is reduced (source: energy star).

So every air conditioner is designed to run at optimum efficiency only if it is used as per the right size. So always size the air conditioner properly. You can use the calculator available at this link before buying an air conditioner: http://www.lg.com/in/support/ac-tonnage-calculator.

If you are not sure about what size to buy, you can always buy an inverter technology air conditioner, as it adjusts to the size and requirements of the room automatically, and thus makes optimum electricity consumption. To check more about inverter ac see our article: Air Conditioners with Inverter technology can help save electricity.

Look for the right options in the air conditioner

In a previous article (Various modes for running air conditioners and their impact on electricity bill) we discussed about various modes of air conditioners and their impact on electricity consumption. It is very important to figure out if the air conditioner has all the modes as per your requirement. If you live in humid area, a dry mode is important. Any air conditioner with energy saver mode and features should be preferred.

Star rating is for real

BEE Star rating of air conditioner does matter a lot. Any air conditioner would consume anywhere between 1-2 units per hour of usage based on tonnage, efficiency and size. Which means if it is used for 10 hours per day, it can consume about 10-20 units in a day or 300-600 units a month (for 10 hours of use daily). At an average rate of Rs 6-7 per unit (you can check your per unit rate using our calculator: Online Electricity Bill Calculator – For all states in India) it can be close to Rs 1800-4000 per month. If your usage is high then the yearly cost of an air conditioner can go very high. In case of high usage, incremental cost of buying a higher star rated air conditioner can easily be recovered in a few years. Please note that the air conditioner will work for at least 10 years and the electricity prices are on a rise. Buying an efficient one while buying a new air conditioner can prevent a lot of heartburn for you in future.

It is important to make a right decision while buying an air conditioner, as it is a long-term utility for you. Do not let lucrative deals, discounts and persuasion by a sales person impact your decision to buy an efficient appliance. A wrong decision on an appliance like air conditioner can significantly impact your electricity bills. We are trying to work out a calculator that can help you choose the right air conditioner for you and hope to release it soon. Till that time you can check the list of top ten most efficient air conditioners at: Top Ten Air Conditioners in India by electricity consumption and size.

    Dear Team, Please guide me

    I have finalized Two refrigerators based on the fuel consumption and capacity. Please guide me which one of the following two I have go for:

    Samsung – Model RT47H567ESL/2015 &
    Hitachi – R-V660PND3KX/2015

    Regards,
    Jayesh

    • Bijli Bachao Team

      Hello Mr Jayesh,

      RT47H567ESL is BEE 4 star with annual electricity consumption of 296 units
      R-V660PND3KX is BEE 4 star with annual electricity consumption of 339.

      But RT47H567ESL is a 462 lts model while R-V660PND3KX is a 601 lts model. So two are quite different.

  • Rahul Haldar

    Respected Team Bijli Bachao,

    I Am From Kolkata And My Room Size Is 11 By 11. I Have Installed A Panasonic 1 Tonn Split Air Conditioner 2 Months Back And Has Set The Temperature To 27 In Cool Mode And It Get Used For Around 12 to 16 Hours A Day.. My Electricity Bill Is Now Coming Somewhere Around Rs. 1500 Per Month. Is It Appropriate???

  • Rashpal Singh

    Sir for my 12′ x 13′ room at ground floor with only south side wall exposed to sunlight , is one ton inverter ac is sufficient , because at start it almost run on about 1400 watt (which is equal to 1.5 ton ac) then gradually going down to 1000 watt and more lower. please advice me. i am going for carrier superia 365 brand

    • Bijli Bachao Team

      Hi Rashpal,
      Which city do you live in? 12*13 room would require a 1.5 ton AC in most of the places. A 1 ton inverter can extend upto 1.2 tons max. 1400 watts is the power consumption of the AC, and not the cooling capacity. If you can tell us the city, we can tell the required amount of tonnage for your room.

    • Rashpal

      sir i live in jalandhar punjab

    • Bijli Bachao Team

      For 12×13 room in Punjab, you would need a 1.5 ton inverter AC. A 1 ton inverter AC will not be sufficient. You can go for a Carrier Superia 1.5 ton inverter AC.

  • Naresh

    Hi my name is Naresh planning to buy a A.C first time . My room size is 10*9. So i am just confuse which A.C I should buy either split AC or Window Ac. I have window also in my room. So please suggest me sir which one I should buy and also the power consumption ?

    • Bijli Bachao Team

      Hi Naresh,

      If your main concern is electricity consumption then you will get better options in Split ACs. You can go through our video that explains more about window vs split: https://www.youtube.com/watch?v=Qx7kgN87i3I ….. all I would say is that manufacturers are slowly moving completely towards split ACs. However there are several factors that one need to consider while buying AC:

      1) Tonnage of AC: Depends on several factors, but primarily on size of room, city where you live in, window sizes, people in the room. Oversized AC consumes more electricity, and undersized does not cool properly.

      2) Star Rating: Choice of BEE 5 star/inverter tech or a lower rating depends on your usage of AC. If your usage is more than 1000 hrs per year (with tariff more than Rs 5), it is better to go for higher efficiency models. Benefit of inverter tech is that it is a variable tonnage AC and as the tonnage requirement is different every month and every day, this AC auto adjusts to the needs and thus saves electricity.

      3) Brand: Some brands offer better reliability/technology and some have better service network. One has to factor in both. Once you have decided on star rating, the most efficient models from good brands can be selected.

      If you provide us with more details as in which city you are in, what is the size of your room, which floor they are on, is there any floor above it, are the walls exposed to sun, usage in hours per day and months per year, and approximate budget, then we can suggest you something.

    • Naresh

      I stay in Secuderabad , and my house in ground floor and in my room has one window is there. And my room size is length-12” and breadth 13”. Mostly I use in summer why because on summer it causes more heat in our room. So please suggest us a good AC either window or Split with power consumption as I am a normal family member.

    • Bijli Bachao Team

      Hi Naresh,
      According to our calculation your room requires a cooling of about 1.4 tons. What is your budget for AC? And what is your usage of AC in hours/year?

  • Ramanathan

    The biggest point seems left out between Window and Split Ac is its maintenance especially of the Out door unit / Condenser Unit in a split which is prone to nuisance from birds & cats and even insects. The insulation widely used for insulating the copper tubes are of such inferior quality that within a few months of the first summer it is damaged. The insulation tube is required to be EPDM rubber which is strong and does not get affected by rain or shine.
    If the tubes get heated up or damaged the very functioning of the split AC is badly affected leading to expensive repairs.
    The installation is outsourced. 99.99% of these installation guys are most unreliable and unscrupulous. They use very cheap to cheap quality of copper tubes and insulation materials thus leading to lot of troubles in the medium run.

    • Bijli Bachao Team

      Thanks for the feedback Mr Ramanathan. Certainly a very important point. Installation is one big issue for split units. Installers are not well trained to install the ACs properly and that causes loss in efficiency.

    • Ramanathan

      Thanks for appreciating the points raised by me. It is noteworthy that the installers use substandard and low quality insulation material. The copper tubes used are often inferior quality. The thickness is dubious so much so they even get punctured easily even during installation. All these have a STRONG BEARING on the power consumption.

  • Vijay

    Can you please suggest which A/C is of low maintenance. I understand O’G or Daikin are good. Is it so?

    • Bijli Bachao Team

      Both General and Daikin are good. However rather than just brand, you should also look at model, its efficiency and features.

    • Vijay

      Yes true. I actually had a Voltas AC for last 4 years and had spent almost the AC cost on service/maintenance. So I am really looking for some ac which will stand good for few years, no/low maintenance cost.

      Kindly advise the best 1.5 ton ac for Chennai all year hot weather.

    my room size is 16 feet X 10.5 feet. Can I use 1.5 ton 5 star split Ac/window AC. Which is better

    • Bijli Bachao Team

      Hi Sanjay,
      Which city do you live in? And is your room on the top floor with direct sunlight falling on the ceiling, or is it on a lower floor? We generally do not recommend people to go for window AC as there are very less efficient models in window ACs.
      The choice whether you should go for split/window AC will depend upon your usage. What is your usage of AC in hrs/year?

  • Rajarshi

    I have a 220 sq foot room (13*17) just below the roof here in Kolkata. Temperatures soar around 37-38 degrees. Which AC would be ideal for me?

    • Bijli Bachao Team

      Hi Rajashi,

      You should go for at least 2 ton AC for your room. An inverter tech AC would be good if your usage of AC is high as tariffs are quite high in Kolkata.

    • Rajarshi Ghosh

      Any recommendations about which brand of AC’s I should target?

    • Bijli Bachao Team

      Hi Rajarshi,
      If your usage is high say above 1200hrs/yr you should go for 2 ton inverter ACs.

  • Chiranjit Pal

    My room’s dimension is 10*13 (roof exposed to sunlight) at south-east corner with two 3.5*4.5 window and two door; another room is 8.5*11 (also exposed) at south with with one 3.5*4.5 window and one door , for two peoples in each room at Burdwan,WB. Need to operate at night preferably (at weekend day time). ACs will be used for 4 months 5-6 hrs at summer time. Please suggest ACs with model no. and good service at Burdwan around 25-35k. Is Blue star multi-inverter AC will be useful?

    • Bijli Bachao Team

      Hi Chiranjit,
      Your bigger room requires a cooling of 1.1 tons during night. And about 1.4 tons of cooling during peak summer daytime. Your smaller room requires cooling of 0.8 tons during night, and 1 tons of cooling during daytime.
      Bluestar is a good brand but its 1 ton inverter AC is not highly efficient. For your usage you can go for BEE 5star AC. But at your budget you can go for 1/1.1 ton inverter ACs for both your room, an inverter AC is about 30% more energy efficient compared to BEE 5star AC, and it will also be able to cool your room during daytime in the weekends.

      You can look at these 1/1.1 ton inverter ACs within 35k:

      brand model eer_ratio tonnage price
      SHARP AH-X13PET 3.83 1.1 32346
      SHARP AH-XP13LV 3.83 1.1 31700

      Bluestar inverter AC has an efficiency of 3.19 and its price is about Rs39735.

  • Suvendu

    Hi, In my village house the power hovers around 150v. We are looking for a split AC that can operate in low volts (Window is not an option because of window/wall positions). As of now what I learned is Split Ac cannot work. Please suggest if there is an option including efficient stabilizers or so.

    • Bijli Bachao Team

      Hi Suvendu,

      As discussed, you should look at Samsung triangular inverter AC. It has a operating voltage range of 148 to 290V.

  • Lalji Patel

    Dear BB team,
    1st of all, thanking for sucha an useful information and research!! Appreciate this.
    I am living almost close (newly built) area of Ahmedabad, doing night shift. I am looking for a split type of AC, most of the use of it during day time as we r doing night shift.
    My house is an individual two storey small building. My bedroom is on 1st (top) floor, on the terrace we have tiles but guessing most of the heat effecting from the back and front rather than top. Temprature remains high (almost 45) during summer. My room size is just small (9X8 feet) one single glazed window! Enters sunlight till 11am. And we r only two in the room.
    Can you suggest us a proper split type of AC according to our room, less energy consuming, less noise making(as the area is very very peaceful)
    Auto temp. maintaining (auto on-off while sleeping mode).
    Budget is 25-30K.
    Really appreciate once again for the time and research.
    A big thank

    • Bijli Bachao Team

      Hi Lalji,
      According to our calculation your room requires 0.8 tons of cooling. So we recommend you to go for 0.75/0.8 ton inverter or 5star AC.

      You can look at these 0.75 ton inverter AC:

      brand model eer_ratio price
      DAIKIN FTKE25GV1 3.35 27490
      PANASONIC CS-YS9RKY 3.38 33390

      If you can get any of these 0.75 ton inverter AC in your budget it will be best for you, If not you can look at these BEE 5star 0.75/0.8 ton ACs.
      You can look at these 0.75/0.8 ton BEE 5star AC:

      brand model eer_ratio tonnage price
      MITSUBISHI ELECTRIC MS-GK10VA 3.65 0.75 26603

  • K L JAIN

    in furtherance to my query will u please suggest which ac is better out of o general,mitsubishi,diakin or hitachi & whether there is difference between indian manufactured piece & lmported one.Also whether inverter ac gives lower energy efficiency after some time of use say one year or it is amenable to more repairs as compared to normal split a.c

    • Bijli Bachao Team

      Hello Mr Jain,

      The list we gave you is arranged based on energy efficiency. General, Mitsubishi, Daikin and Hitachi are all top brands and all of them have their own postives and negatives (you can choose the model as per the list we provided based on your budget and brand choice). In general imported ones are considered better although we do not think that India made are bad. There is no proof that inverter ACs give lower efficiency after one year. If you maintain it regularly (get regular cleaning done) then there is no reason for it to significantly decrease in efficiency. Normal derating happens for every AC (top brands have lesser derating). Maintenance is a bit more expensive for inverter AC (AMC for my 0.75 ton inverter AC costed me Rs 500 more per year than regular AC) however electricity savings far outweigh that. They are not amenable to more repairs but spare parts are expensive (it is important to protect them from power surges if they happen in your area). We have been suggesting inverter ACs to people for 3 years now and we have not heard any such complaints other than hearing people telling us stories about dealers suggesting them not to go for inverter AC as parts are expensive.

  • Siddarth pal

    we have two separate rooms with 10*12 (roof exposed to sunlight) and 10*10 (not exposed) for two peoples each at Burdwan,WB. Need to operate at night preferably (seldom at peak times). Please suggest ACs with model no. and good service at my place.

    • Bijli Bachao Team

      Hi Siddarth,
      According to our calculation your first room(10*12) requires a cooling of 1 tons during night time and 1.3 tons during daytime. And your second room(10*10) requires a cooling of 0.9 tons. Since your usage is mostly at night you can go for 1 ton ACs for both your room.
      The type of AC required for your room will depend on your usage and budget. What is your usage of ACs in hrs/yr (separately)? And your budget for two ACs?

    • Siddarth Pal

      ACs will be used as minimum as possible and it may be about 90 days during summer at 4-5 hr/day. My budget is near about 30-35k each.

    • Bijli Bachao Team

      Hi Siddarth,
      Your usage is low so we recommend you to go for BEE 3star 1 ton AC.

      You can look at these BEE 3star 1 ton AC:

      brand model eer_ratio price
      HITACHI RAU412HTD 3.29 29100
      HITACHI RAU412KTDP 3.29 32999

      DAIKIN FTC35PRV16+RC35PRV16 3.25 27777
      MITSUBISHI ELECTRIC MS-HK13VA 3.24 27200

      At your budget you can also get 1/1.1 ton inverter AC. They are about 40% more energy efficient compared to a 3star AC. And a 1.1 ton inverter AC can extend upto 1.3 tons, so you can use it to cool your bigger room even during daytime. Tell us if you require a list of 1/1.1 ton inverter AC.

    I have a room 10*12 sqr feet on 2 floor which is not direct to soon light.estimated consumption for 4 people on daily basis is 5-6 hours (MAX).Can you please suggest which company AC i will go for.My budget is around 30k.Is Panasonic/voltas/blue star are good companies to go for AC. Please suggest.

    • Bijli Bachao Team

      Hi Rahul,
      Which city do you live in? For how many months are you going to use the AC?
      Panasonic/voltas/blue star all are good brands.

    • Rahul Sharma

      Hi BB team , i am living in navi mumbai.

    • Bijli Bachao Team

      Hi Rahul,
      According to our calculation your room requires 0.9 tons of cooling. So we recommend you to go for a 0.75/0.8 ton inverter AC. Tariff in Mumbai is high and inverter ACs save about 30% electricity compared to a normal BEE 5star AC.

      You can look at these 0.75/0.8 ton inverter AC around 30K:

  • santosh

    Hi, my flat on 7th floor on 8 floor building west side of flat is open.Sunlite directly comes on west side wall & window. I have two 100sqft room and one 150sqft hall in kolkata. I want best best energy efficient inverter or 5 star split or window ac. kindly suggest me the capacity and best available option.

    • Bijli Bachao Team

      Hi Santosh,
      According to our calculation your room two 100sqft room requires 1 tons of cooling. And 150sqft room requires 1.5 tons of cooling. We generally do not recommend people to go for window ACs as there are very few efficient models in window AC. You can go for a 1/1.1 ton inverter or a BEE 5star 1 ton AC for your two 100sqft rooms. And a 1.5 ton inverter or a BEE 5star 1.5 ton AC for your 150sqft hall.
      Whether you go for an inverter AC or a BEE 5star AC depends on your usage. If your usage of AC is greater than 1200hrs/yr we recommend you to go for an inverter AC. If it is less than 1200hrs/yr you can go for a BEE 5star AC.

    • Ridham

      Dear Sir,
      I am thankful to you for providing valuable information regarding every field to us, Sir I wanted to know which company is best in Manufacturing A/c, Mitshubishi Electric (ME) or Mitshubishi Heavy Duty (MHD)? What is the difference between them ? Some seller say that ME is assembled in India, some say MHD is imported totally from Japan etc,., And even wanted to know whether Air conditioner with heat pump is successful in Ahmedabad,Gujarat. As I am planing to buy such A/c but some seller are advising me not to buy such combo a/c as they are not successful in Ahmedabad.

    • Bijli Bachao Team

      Hi Ridham,

      There is nothing like best brand in ACs. Everyone has some good things and some bad things. Between Mitsubishi Electric (ME) and Mitsubishi Heavy Industries (MHI) the general perception is that MHI is better as it is mostly imported. However MHI is not a widespread brand and if you are in a small place, getting service might get difficult.

      A heat pump based AC would be good for you if you have a requirement of using room heaters in winters. I do not think Ahmedabad gets that cold that you need a room heater. Heat pump is 3-4 time more efficient than regular room heater. But I doubt you would be needing it in Ahmedabad. So it is not of much use to you. It will be better if you go for regular AC.

    • Ridham

      Thank you Sir

    i nave a bedroom which is made by joining two rooms(200 sq ft).which ac is preferable window or split,What capacity. it is in delhi.

    • Bijli Bachao Team

      Hi Danny,
      Is your room on the top floor with direct sunlight falling on the ceiling, or is it on a lower floor? What will be your usage of AC in hrs/yr? We typically do not recommend people to go for window ACs, as the star rating of window AC is one level lower than that of split AC.

    • danny

      Yes d sunlight effect is directly on d ceiling.. Can uh provide me list of 5 star ac’s whichconsumes less electrricity up to 35k

    • Bijli Bachao Team

      Hi Danny,
      According to our calculation your room requires 2.2 tons of cooling during peak summer daytime, and 1.9 tons of cooling during night. In your budget you can get only BEE 5star 1.5 ton AC. We recommend you to keep the AC close to your bed so that it provides local cooling. It will work well at night and also relatively well during daytime.

    i nave a bedroom which is made by joining two rooms (14×15+12×12=354 sq ft) should i have one AC or two ACs. What capacity. it is in bhubaneswar. west side window. Does window AC give you more oxygen? Should I have one split and one window AC?

    • Bijli Bachao Team

      Hi Santosh,
      Is your room on the top floor with direct sunlight falling on the ceiling, or is it on a lower floor? What will be your usage of AC in hrs/day and months/yr? And what is your budget?
      Window AC does not give more oxygen compared to a split AC.

    • santosh

      The larger portion of the room (15×14) has a room above it. The rest (12×12) is exposed roof, but shaded for most part of the day by neighboring building and trees. AC needed during afternoon (12 noon till 4pm) and night (10 pm to 6 am)

      thanks.

    • Bijli Bachao Team

      Hi Santosh,

  • Rahul Sharma

    Hi BBT,
    I am living in Rajasthan. Can you please suggest Split/Windows AC(which is best and consume less power in budget of 30-45K) for a Big hall(54*16) which is on ground floor whose ceiling is direct to sun light.Count of people can be 5-6 which will be in the hall and It can used for 8-9 hours in a day(8am to 5 pm and in day for 4 hrs for alternate week-so approx it will be 2500 hrs / year).

    • Bijli Bachao Team

      Hi Rahul,

      A 54×16 hall would need 10 tons of cooling. The only way to fit 10 ton in 30-45 K would be if you go for second hand ACs. And it will be impossible to get power saving ACs in that money. As you are in Rajasthan, would suggest you to go for desert coolers instead.

  • puneet

    Planning to buy a split ac for home , should be silent , the room size is 14*13 . Room has a little sunlight during the day on the roof. The approx usage is about
    1000-1100 hr/yr .Budget around 35k+ ,Could stretch the budget to go for an inverter ac , if its worth it . Need a durable ac .Which one is best in terms of maintenance ,durability, energy efficiency?

    • Bijli Bachao Team

      Hi Puneet,
      Which city do you live in?

      I am from Punjab ,the temperature in the peak is around 45+

    • Bijli Bachao Team

      Hi Puneet,
      According to our calculation your room requires 1.7 tons of cooling. So you can either go for 1.5 ton AC inverter AC or a BEE 5star 1.7 ton AC. It will cost you about 45K. Or you can go for a BEE 5star AC and keep it close to your bed and it will work well during night time though it may fall bit short during peak summer daytime use.

  • Gaurav Sharma

    Dear Bijli Bachao Team!

    Greetings

    I’m Gaurav from Chandigarh and I’m planning to buy an Air Conditioner these summers. Little confused between a split AC and a Window AC.

    My room is 14×16 feet. Their is also an adjoining room with a door in between. I want the decent amount of cooling in other room as well. It faces. The room where AC is to be installed is balcony facing and is on top floor. Sunshine remains there for most of the daytime.

    My usage will be for evening and night only. PLease suggest some good options between ideal price range.

    Thank you!

    • Bijli Bachao Team

      Hi Gaurav,
      According to our calculation your room requires 1.9 tons of cooling during night time. What will be your usage of AC in hrs/yr? And what is your budget?

    • Gaurav Sharma

      Usage is expected to be around 3000 hours in a year. Budget is somewhere between Rs 25-28000.

    • Bijli Bachao Team

      Hi Gaurav,

      As per our calculation your room needs 1.9 tons of cooling during peak summer day time. However it is extremely difficult to get a good efficient AC of that size in your budget. Also your usage is extremely high which makes going for an energy efficient AC a must. We would have strongly recommended you an inverter tech AC, but your budget is way too low for that (almost half). The best that we can think of is going for a Kenstar BEE 5 star rated 1.5 ton AC which is available on Amazon for 26K. It has EER of 3.51 which is good and budget wise it will fit in your budget. You can look at this link: http://www.amazon.in/Kenstar-KSM55-WN1-Split-Rating-White/dp/B00Q9X8HHA

  • Rajesh

    Hi, I am from Chennai . We have a Samsung window AC for the last 6 years and suddenly it stopped working and after checking we found that the compressor is gone. Asked us to go for a new one as no use of changing with a new compressor.
    I want to go with a Split AC. My room size is 10ft x 12ft with 2 windows and 1 door in the room. Can you please suggest right model and tonnage of the AC for power saving. Lot of my friends are suggesting to go with 1.5T Split AC of Daikin, Hitachi or O-General compared to other brands. Can you please sugegst for Chennai Area.

    • Bijli Bachao Team

      Hi Rajesh,
      is your room on the top floor with direct sunlight falling on the ceiling, or is it on the lower floor? And what will be your usage of Ac in hrs/yr?

  • SAM

    I live in Delhi where during peak summer days, temperature hits 45C. I was thinking of an AC under 35K. I would most likely use it for 5-7hrs for 120 days. I was thinking if an inverter AC or a 4-5 star AC is a better option. Also the room where it would be installed is around 13 X 19 feet. I also want a brand (does the brand count?) that I could rely on for maintenance.

    • Bijli Bachao Team

      Hi Sam,
      Your room requires a cooling of 2.3 tons if it is at lower floor. If it is at upper floor with direct sunlight it will require a cooling of 2.9 tons during peak summer daytime. At your budget you can get a BEE 5star 1.5 ton AC which will be ideal for your usage. If your usage is at night only it will work fine if you keep the AC close to the bed. It will cool the area near the bed and surrounding area near it.

    • Sam

      Thanks, but are the prices the latest?? And wouldn’t you recommend inverter ACs? Or is having a 5 star rating ac ok?

    • Bijli Bachao Team

      Hi Sam,
      Yes prices are up to date. But they keep on changing regularly so cannot guarantee that you will get the AC at the mentioned price. 1.5 ton inverter AC costs about 43k. For your usage a 5 star AC would work well.

  • Kishore

    Hi … I stay in Mumbai , the average temperature would be 32 degrees (Approx) in summer days not sure of the humidity part , the room size would be 350sq , as i stay on the top floor there is direct sunlight thought out the day (the most being in the afternoon 2 – 5 pm directly from the window) , also could you please advise me on which ac should i buy window or split (i stay on a rented apartment) , i have seen few brand (eg Blue Star / LG / Voltas / O General ac)

    • Bijli Bachao Team

      Hi Kishore,

The usage of the Ac would be mostly at night except for the weekends , sorry a small correction on the room size …. the room size is 150 sq ….. and regarding the budget … anything upto 30K …. basically i am looking for 1.5 ton ac with 5 star rating ….. also i am told that window ac are less in maintenance then split ac …. kindly help me on choosing an ac which would be good for a long term use …. Thanks

    • Bijli Bachao Team

      Hi Kishore,
      According to our calculation your room requires a cooling of 1.3 tons during peak summer daytime. So we recommend you to go for a 1.1/1.2 ton BEE 5/4 star window AC. It will work well during daytime use also and will fit in your budget.

    Hello BB Team,
    We are planning to buy ac for two rooms of size 15 X 15 and 11 X 12, ground floor, direct sunlight , city – Gurgaon, 4 members:
    Usage for room ( 15 X 15 ) + lobby attached will be occasional ;
    Usage for room ( 11X 12 ) will be usually in night ( 8 pm to 5 am) and in day for 4 hrs for alternate week . so approx it will be 2500 hrs / year.
    Please suggest good a.c acc. to you and also clear my confusion of choosing b/w Split & Window ac, though I have read the article but still confused as I am told by many that Split is more complex and overall expensive in terms of install/uninstall . However, in terms of performance both are same . After knowing all this , I was planning to go for window ac
    Budget: 40K Around
    My query : How much is this true ? Need your valuable guidance in choosing one.

    • Bijli Bachao Team

      Hi Ritu,
      According to our calculation your room (11*12) requires a cooling of 1.5 tons. Your usage is very high and at your usage we would recommend an inverter AC but it would cost about 43-45k. At your budget you can get a BEE 5star 1.5 ton AC which at your usage would not be much efficient.
      Your second room requires a cooling of 2.5 tons and you need at least a 2ton AC which will cool the room partially. A BEE 3star 2 ton AC would cost about 40-45k.
      At your usage we recommend you to go for split AC only window ACs are less efficient than split AC.

  • nita

    Sir,
    I want to install ac for only summer purpose.. my room size is 16*13 ft. One wall diretly sun facing after forenoon… My budget is 25-30k. Is window ac good for our room?? How much ton ac required fir my room?? Plzz huggest… There are 5 window and 2door in my room… I stayed in kolkata

    • Bijli Bachao Team

      Hi Nita,
      Is your room on top floor with direct sunlight falling on the ceiling, or is it at lower floor? And what will be your usage of AC in hrs/yr? (This is important to calculate the tonnage and the right model of AC for your room)
      Typically we recommend people to go for split ACs as the BEE star rating of window AC is one level lower than that of split AC.

    • nita

      My home one storied… 400hr/yr usage needed normally.. ya sun light put on celling also…

    • nita

      Yes sir sun light falling on roof also as my home is one storied building… Most probably 400-450hr/yr ac will be used.. is it possible to hv a split ac in my budget??

    • Bijli Bachao Team

      Hi Nita,
      According to our calculation your room requires 1.8 tons of cooling if your usage is at night only. For peak summer daytime use it would require 2.3 tons of cooling.
      So we recommend you to go for Kenstar KSM55.WN1 BEE 5star 1.5 ton split AC its price is around 26k. The AC will work well, though it may feel bit short during peak summer at night time use. But you can keep the AC close to the bed and it will be able to cool the area around bed. For daytime use 1.5 ton AC would be insufficient for your room.

    • Bijli Bachao Team

      Hi Dipesh,

    Hi,

    I have a query.. I plan to buy a Split AC,
    Room Size 10×10 sq ft.
    I stay on a middle floor.
    Usage is 7-8 Hrs a day for 5 Months.
    No windows, only two doors in the room.

    *There is a Big sewer Drain, in proximity of 600-700 Mtrs from our home, which make the Gas leakage a problem in AC’s.

    Which AC’s do you recommend?

    Hi,
    We are planning to buy AC for our Office. It is approx 650sqft . Two Full partition which covers around 30% area and remaining area has half partition.
    On First Floor.
    Yes Direct Sunlight
    Please suggest which Ac should we go for and how many
    Can we consider buying second hand Ac..

    • Bijli Bachao Team

      Hi Anuj,

      Will it be possible for you to send a diagram of the layout on [email protected]? Each full partition would need separate AC. But for that we need to understand the area for each partition.

    • Anuj

      Hi,
      Have Send the mail.

    • Bijli Bachao Team

      Hi Anuj,
      After looking at the picture we think that your back office requires 0.8 tons of cooling, and MD cabin requires 1.1 tons of cooling, And the rest of the space requires 4 tons of cooling. Since its an office we assume that the usage is going to be high we recommend you to go for 0.75 ton inverter AC for back office. 0.8/1 ton inverter AC for MD cabin. and two 1.5 ton inverter ACs for the rest of the space.
      We would not recommend you to go for second hand AC as chances of getting an efficient second hand AC is less. Can you tell us what is your budget so that we can recommend the ACs suited for you.

  • Chetan

    Sir,

      Hi Chetan,
      According to our calculation your room requires 0.8 tons of cooling. Since your usage is low you can either go for a BEE 3Star split 1 ton AC or a BEE 5 star 1 ton window AC. As the BEE star rating of window AC is one level lower than that of split AC.

    Hi,
    Nice content.
    I am planning to purchase split AC, need your suggestion.

    Leaving in pune and bedroom size is (13*11). Please suggest which split AC suitable.

    • Abhishek Jain

      Hello Dhaval,

      Is your house on top floor or middle floors (i.e. do you get direct sunlight on the ceiling of the bedroom)? Also do you get direct sunlight on any of the walls during the day? How much is your usage of AC in hrs/year (hrs/day and month/year will also help)? and finally how much is your budget?

    • dhaval shah

      Hi
      Thanks for Reply. House is at middle floor. No wall getting direct sunlight. Usage will not be much, mainly in summer and that is 4-5 hrs. Budget is 30000-40000.

      Suggest also which brand and capacity.

      Thanks in Advance,

    Dear Team,
    I need Split Ac for my flat at Navi Mumbai, which is on 8th Floor in the 12 storey building. Hall & 2 bedrooms are all in the same line & each room gets morning sunlight.
    – Hall ( 20*12)
    – 2 bedrooms (10*12)
    Which is the best brand & energy efficient Split Ac you would recommend me for hall & bedrooms ??
    Regards,
    Navin.

    • Abhishek Jain

      Hi Navin,
      According to our calculation your hall (20*12) requires 1.7 tons of cooling. So you can go for an 1.5 ton inverter AC.
      For your two bedrooms of (10*12) requires a cooling of 0.8 ton. So you can go for a 0.75/0.8 ton inverter AC for both the room. Inverter ACs are the most efficient ACs available in the market.

  • Amit Shukla

    Hi Abhishek
    This is Amit Shukla. I live in Gurgaon. I am looking for an Split AC for my living room. My budget is around ~26K. Following is room size detail:
    Room size: 18X12 ft.
    2 Windows in room with size: 6X6 ft each
    3 doors
    Room is East and West Facing

    I came across an Kenstar KSM55.WN1 Split AC (1.5 Ton, 5 Star Rating, White) on Amazon.in which is fitting in to my budget. But I was not sure how good this AC is in terms of durability, quality, post sales support and most importantly EER

    I need your help with answers to following query

    1. How is this Kenstar AC being sold by Amazon? is it really good product in overall quality against its low cost that it is boasting off?

    is it worth to go for it?

    2. Could you also recommend some other best products available which are good in quality which could suit my requirements and budget

    Please help suggest. I need to buy an split AC for my room ASAP.

    Thanks
    Amit Shukla

    • Amit Shukla

      In continuation to previous query, My AC usage would be roughly around 5-6 hours per day for around 6 months in a year

    • Abhishek Jain

      Hi Amit,
      According to our calculation if your room is on ground floor it requires 2 tons of cooling. If it is on top floor (with direct sunlight falling on the ceiling) it would require 2.5 tons of cooling. A 1.5 ton AC would be undersized for your room it would only provide local cooling (it will just cool 7-8 feet around the AC). It will be difficult to get a 2 ton AC in 26k budget. As far as Kenstar is concerned it is a new brand we do not have much user feedback about it so we cannot comment on Kenstar.

    • Amit Shukla

      Thanks so much Abhishek for your reply. My apartment is at 1st floor with 3 sun facing sides. Ground floor is used for Parking.
      Correction: Window size would be 4X4 Sq ft with glasses fitted in it.

      According to your suggestion, if I have to go for 2 Ton AC. I will try to stretch my budget and go for

      Could you please advise me some low budget 2T AC options but good as well in terms of durability,quality and after sales support?

    Will R22 gas banned in future?

    • Abhishek Jain

      Will take a long time. May be in next 15-20 years. Phase out of R22 has begun. More ACs coming up with R410 and R32.

  • Syed Usama Ameen

    Hi Abhishek
    Hope you are fine. we are planning to make our four room air conditioned.
    first room ground floor 12×10 (120 sqr ft) 11 ft (height) no direct sunlight, 2 persons 3 hours a day
    second room first floor 12×10 (120 sqr ft) 8.5 ft (hght) no direct sunlight, 5 persons 10 hrs a day.
    third room top floor 12×10 (120 sqr ft) 11 feet (hgt) exposed to sun from top eastern and northern sides 5 persons 4 hours a day.
    fourth room top floor 12×12 (144 sqr ft) 8 ft (hgt) exposed to sun from top and southern sides 2 persons 4 hours a day.
    we seek your advise regarding tonnage, type (single split-multi split), technology ( traditional-inverter) we want energy efficient economic and value for money appliance (preferably 5 starer) suggest the brand if you could keeping our requirements in view. meanwhile we have been listening good reviews about daikin and blue star former seems a bit expensive comparatively. is it worth it?
    we are awaiting your response.

    Regards

    • Abhishek Jain

      Hi,

      Which city is this for? Both Daikin and Blue Star are great brands with good reliability. Daikin is Japanese whereas Blue Star is Indian. However if we look at energy efficiency, then Daikin products in general have higher energy efficiency ration as compared to Blue Star in the same star rating range. But I would say it would depend on the size requirement of your room which I can tell only when I know your city.

    • Syed Usama Ameen

      Hi,
      First of all Many thanks for your quick and valuable response. i should have mentioned it in earlier correspondence anyway i am put up in Mumbai. eager to know your calculations and suggestions.

      Thanks again

    • Abhishek Jain

      Hi,

      Here are my calculations:

      1) Room 1: As per my calculation 0.9 ton cooling is required. So 1 ton AC should be good. Usage of the AC is less (I guess it is less than 600 hrs/year), so a regular AC would be good.

      2) Room 2: As per my calculations 0.8 ton cooling is required. Usage is also high, so 0.75 ton inverter AC would be great for the room.

      3) Room 3: As per my calculations 1.2 ton cooling is required. Again I think usage is less (less than 600 hrs/year), so regular AC would be good.

      4) Room 4: As per my calculations 1.2 ton cooling is required. Again I think usage is less (less than 600 hrs/year), so regular AC would be good.

      If you go for multi split a 3.5-4 ton multi split inverter AC would be good for 4 rooms. Daikin, Sharp, Bluestar have options in multi split inverter but I am not sure of the prices.

      Daikin and Bluestar both have good BEE 5 star rated models and you can go for any brand of your liking. In Inverter AC of 0.75 ton I would suggest you to go for Daikin.

  • Pooja

    Hi Sir,

    We plan to install split AC in our room which is a small room of 8*8 sq feet as well as in other bedroom which is 10*8 sq feet approx. We already have AC in the third room, hence for these two rooms we plan to go for one dual Split AC wherein it will have 2 vents one in each room which can function simultaneously so both rooms would be sufficiently cooled. The reason being, buying again 2 different ac’s for 2 rooms would be costly affair . Leave alone the electricity bill for 3 ACs in one house. Can this or similar option be workable? If not what other options can be thought of.

    Thanks in advance for your reply.

    • Abhishek Jain

      Hi Pooja,

      Typical multi split ACs have 3 or more indoor units. I have not seen one with two units. Also if you are going for multi split it is better to go for one with inverter technology. Your rooms would not need more than 0.75 tons of cooling each or 1.5 tons in total. You can check Sharp, Daikin, LG they have multi split inverter AC options.

  • Mridul Singh

    Hi Sir,
    I just want to know about Godrej GSC 18FG 6 ONG & GSC 18FG 6 WNG

    1. These are 6 star or 5 Star ?
    2. Compressure is good or not (for both) ?

    pls, help me sir at the earliest.

    THANKs a Lot .

    • Abhishek Jain

      Hi,

      There is nothing like 6 stars. BEE only gives up to 5 star. So these ACs are BEE 5 star rated. Compressor for these ACs are good. They are high efficiency because they use R290 which is highly energy efficient refrigerant.

  • C V Pillai

    It is heard that window ac can has got ventilation but split does not have. As a result, window ac is more suitable as it can get fresh air. Is this correct ?

    • Abhishek Jain

      There is no way an air conditioner can get fresh air. The principle on which air conditioner works cannot let you get fresh air from outside. It does not work like an air cooler.

    • Sarang Sarode

      Hi,
      Yes, window ac is more suitable as it can get fresh air. In window ac you can adjust the amount of infiltration (i.e. addition of ambient air ) whereas split ac does not have such provision.
      Window ac does not even cool whole room, it keeps some temperature gradient along vertical direction. It only cools room up-to certain height, depending upon installation height, thus saves energy. If you have sensible hand you can even feel the temperature difference when raise your hand in room.
      In my view the only major disadvantage of window ac is noise. It creates more noise compare to split ac. If you are ok with it then definitely go for it.
      regards,
      Sarang

  • toon

    I am planning to buy a split a.c for my bedroom which 13” * 13.6”. I live in Bangalore. My flat is the 1st floor of a 4 storey apartment.it is north facing and has a window. My usage maybe around 5-6 hours a day but not everyday. Please suggest a cost effective model with good ERR rating.

    • Abhishek Jain

      You need 1.5 ton AC for your room. You can look at these models:

      These are some with highest EER:
      GODREJ GSC 18 FG 6 ONG or GSC 18 FG 6 WNG
      HITACHI RAU518HUDDZ or RAU518HUDD
      LG LSA5AP5M or LSA5ES5M or LSA5MP5M or LSA5NP5F or LSA5SP5M
      SAMSUNG AR18HC5EXLZ or AR18HC5TXNC or AR18HC5TYUR

      However as a brand japanese brands (Hitachi, Daikin, Panasonic, General, Mitsubishi) + Carrier + Blue star are quite durable. You can go for any japanese brand BEE 5 star rated model as well.

    • Abhishek Jain

      Hi Santosh,

      Which city is this room in? Also does the ceiling get direct sunlight? Also how many months in a year would you use it?

  • Karan Shah

    Sir,
    I am planning to buy 2 split ACs one for bed room and another for living room.
    My AC usage is going to be very low. Won’t be used more then 2-3 hours a day in total for both the ACs.
    Please suggest me the best AC for me with such less usage.
    Shall I buy 5 star rating or inverter?
    If possible please do explain what types of AC to be bought on different usage parameters.
    Thank You.

    • Abhishek Jain

      Hello Mr Shah,

      There are several factors that one need to consider while buying AC:

      1) Tonnage of AC: Depends on several factors, but primarily on size of room, city where you live in, window sizes, people in the room. Oversized AC consumes more electricity, and undersized does not cool properly.

      2) Star Rating: Choice of BEE 5 star/inverter tech or a lower rating depends on your usage of AC. If your usage is more than 1000 hrs per year (with traiff more than Rs 5), it is better to go for higher efficiency models. Benefit of inverter tech is that it is a variable tonnage AC and as the tonnage requirement is different every month and every day, this AC auto adjusts to the needs and thus saves electricity.

      3) Brand: Some brands offer better reliability/technology and some have better service network. One has to factor in both. Once you have decided on star rating, the most efficient models from good brands can be selected.

      If you provide us with more details as in which size of your room, which floor they are on, is there any floor above it, are the walls exposed to sun, usage in hours per day and months per year, and approximate budget, then we can recommend you something. Hope this helps.

  • Vibhor Sharma

    Hi Abhishek,

    I want to know that what is the benefit of tower AC? Is tower AC are better than split and window AC? I have also seen a Portable AC 1 ton(lloyd company). I want to know that is it good to buy portable AC?

    • Abhishek Jain

      Hi Vibhor,

      Tower ACs are just like split ACs, its just that they do not need any installation on wall but they need space on floor. They are available in larger capacity usually for bigger rooms. Portable ACs are smaller ACs and can be easily moved from one room to another. The only big drawback I see of these two is that the energy efficient technologies are not available in these and thus you will have to live with lower efficiency product that will consume quite some amount of electricity.

  • Marisa Lopez

    Hi

    I would like to know if possible how much it would cost per day to run my LG Inverter that I have in a staff room. In summer it will be on for at least 8hrs (as the room is being leased out as an office) and vice versa in Winter.

    Dear Abhishek,

    First of all… too good effort in running such an informative portal.

    I am looking for an ac for room size 12*15, top floor, east facing, one 8*4 window in east (covered with curtain), no other wall side under direct sunlight, property located in Faridabad. Preferably looking for an inverter tec. ac as usuage in 6-10 hrs a day for six months. please suggest tonnage and brand.

    Regards,
    Dheeraj

    • Abhishek Jain

      Hello Mr Sangal,

      You need about 2 tons of cooling for your room (or 1.8 ton inverter AC). You can look at these inverter tech models:

      You can check these 1.8 ton inverter ACs:
      Daikin FTKP60PRV16
      Daikin FTKM60PRV16
      Sharp AH-X21RET
      LG BS-Q246C8R3
      LG BS-Q246C8A2
      Samsung AR24HV5NBWK

      Or these 2 ton inverter:
      Hitachi Ace Inverter 2 ton
      Mitsubishi Electric MSY-GE24VA

    • dheeraj sangal

      Thanks Abhishek… How about a 1.5 ton invertor of daikin…?? As to save on ac cost, plus it has higher cop and eer as compared to 1.8… Please suggest..

    • Abhishek Jain

      Hello Mr Sangal,

      1.5 ton inverter will work well on most days/nights. But it may fall a bit short during peak summer day time. So on hottest day in summer it may not cool the whole room effectively (will cool area close to the AC, but some parts of the room away from the AC may not feel cool). But otherwise it can work fine. It will be cheaper on cost and will certainly be better in saving electricity all other times.

  • Arun

    Sir,
    We live in tamil nadu, india.
    We have a 2.0 tone Blue star ac (year 2009) fixed with stabilizer and mcp switch.
    we have three phase EB line supply, out of which one phase is connected to AC alone.
    The AC when switched on, after 2 min, it tries to start, but the stabilizer trips it every time.
    The connection is as follows
    EB -> MCP -> stabilizer -> AC
    We disconnected MCP and tried,
    We disconnected stabilizer and tried,
    We even gave EB -> AC direct connection and tried.,
    But AC tries to start, but trips every time.

    when checked with service people of blue star, they changed the capacitor and tried, but again trips every time. But when taken to their service station, the AC runs fine.
    Then i checked EB line. the voltage is between 200 – 240.the amps is between 0 – 3. the power factor is between 0-1
    Why is the AC tripping and not running at all ? how to solve this problem ?

  • Sudhanshu Arora

    Hi sir,
    I am looking to buy an AC for my room on first floor of my duplex.
    room size: 16’x16’x12′ (lxbxh)
    it receives direct sunlight throughout the day. 3 sides plus roof exposed to sunlight.
    ventilation is through one window of 4’x4.5′.
    usage will be around 1000 hours or less per year.
    please recommend which type, tonnage, star rating brand of AC should I go for?
    also the usage may increase in future to 13-1400 hours so suggest for both the cases.
    Thanks,
    Sudhanshu Arora

    • Abhishek Jain

      Hi Rupesh,

      FTKS is a hot and cold AC. Amongst the list FTKP will be good. Or FTKM will be better.

    • Rupesh K C

      Dear Abhishek,
      I m getting FTKS only cooling R410 Gas Thailand made. Also how about SRK12YL-S mitsubishi heavy. ( I think fter sales service is poor, not sure)

      Also please explain if any difference R22, R32 & R410 Gas. Will this have effect on electricity Bill

    • Abhishek Jain

      MHI is a good brand however not highly visible in India. So it is highly likely that its service may not be effective if you are in a smaller city. FTKP and FTKM are better than FTKS (indian made) for cooling. I would still suggest that you go for Daikin. As for gas, it does not have impact on electricity bill, but R32 and R410 are greener and have lesser negative impact on environment.

  • Deepak Mitra

    Dear Abhishek,
    1. Office Space : 10 x 18 2. Area : Delhi, 3 : no. of people : maximum 3, Location : First Floor there is two storey Building, 4. Option : split or window can be installed 5 : Sunlight : no Direct Sunlight 6: Brand : Hitachi/Bluestar/LG/Carrier any..Please suggest

    • Abhishek Jain

      Hello Mr Mitra,

      You need about 2 tons of cooling if the ceiling receives direct sunlight (which I assume is right because you said first floor in two story building). If that is not the case then you need 1.7 tons of cooling. You are on commercial connection and I think you should go for inverter tech AC. In case you need 2 ton cooling then 1.8 tons of inverter AC should be good. If you need 1.7 ton then 1.5 ton inverter tech should be good. You can look at these models:

      1.5 ton inverter:
      Hitachi Ace or Kampa inverter 1.5 ton
      Daikin FTKM50PRV16
      Samsung AR18HV5DAWK

      Sharp AH-XP18PHT, AH-XP18PMT, AH-X18PET, AH-XP18MV
      Samsung AR18HV5NFWK

      1.8 ton inverter tech:
      Daikin FTKP60PRV16
      Daikin FTKM60PRV16
      Sharp AH-X21RET
      LG BS-Q246C8R3

  • Deepak

    hello sir,kindly suggest me a best split ac for a room size of 12*10*10 ground floor,no direct sunlight and there is room above of thjis room,i live in ghaziabad city.so,plz suggest me as per the energy efficient ac whether inverter technology or bee 5 star ac is good for me to installed.
    thanks

    • Abhishek Jain

      You need 1.2 ton fixed speed or 1 ton inverter AC for your room. You can check these:

      1.2 ton AC:
      Hitachi RAU514IUD or RAU514EUDA
      Whirlpool 3D Cool Platinum V or Magicool Platinum V
      Voltas 155 CY

      1 ton inverter AC:
      Daikin FTKM35PRV16 or FTKP35PRV16 (1 ton)
      Hitachi ACE or iClean Inverter AC (1 ton)
      Sharp AH-XP13LV, AH-XP13PHT, AH-XP13PMT, AH-X13PET (1.1 ton)
      Samsung AR12HV5NBWK or AR12HV5DAWK (1 ton)
      Panasonic CS-S12PKYP Econavi (1 ton)

      Would suggest to go for inverter AC.

    • Deepak

      Thanx sir appreciate ur work,also tell about the installation process means what should be the minimum and maximum distance between the indoor and outdoor unit bcoz as I told u before my room is on ground floor but the open area is on the roof of the second floor of height 10 feet each.

    • Abhishek Jain

      Well there is no specific minimum or maximum distance that is mandatory. The pressure of refrigerant in the tubes should be right. If you look at technical specifications of any model, they will give maximum piping distance (mostly about 12 to 15 mts). There is no minimum. It is just that if you increase the length more than that specified, you will have to add extra refrigerant to maintain the pressure which will come at additional costs.

    • Deepak

      Thanx sir for ur valuable suggestions,I have 2 more query to clerify I have a 4kw power backup connection and the load is about 3 to 3.5kw in summers and under 2kw in winters as my electricity bill shows so tell me there is a need to exeed power backup connection to fix inverter technology ac of 1 or 1.5 ton?
      Second question is that according to ur suggestion 1 ton of split ac is sufficient acc to my room size but I want to know I have a separate room of same size beside of this room now I want to install 1.5 ton of ac instead of 1 ton with exhaust fan between the wall of this two rooms,1.5 ton inverter ac is installed in one room and the cool air will pass by the help of exhaust fan into another room for both roomates feels cooling,this is possible or not?
      Thanx once again m eagerly waiting for ur reply.

    • Abhishek Jain

      1 ton inverter AC would add 1 KW and 1.5 ton inverter would add 1.5 kW to the load. Also if you add another room of the same size then the tonnage requirement will double up. So if the room needs 1 ton, then for two rooms, the requirement would be 2 ton.

  • Mandeep singh

    hello , kindly suggest us a split inverter technology AC for a room size of 12 * 12 *10 .( ground floor)
    no direct sunlight .

    • Abhishek Jain

      Which city is this for? Are there any rooms above this room?

  • ravi

    ok so if i have to choose in mistubushi 1.5 tonnes which would be right model that u will suggest .. I have few lg ac in my house but i find their cooling is not that good and also thier energy consumption is high so i certainily am not much satisfied with lg though their service is good … and if u have any personal experience with 1.5 tonne ac then suggest that company model too and also let me know abt its service bz thats the biggest pain in a$$ with many companies bz its electrical stuff and so there is bit of luck too as some times best companies ac peice are faulty for u but may be good for others… and i will also go to shop and will get some models code and will let u know too and then i can ask best among those …….. And ya one more thing i was discussing with my brother abt 3 star and 5 star … he said that energy saving is not as much compared to the models rate differece and by the time i buy ac next time insteaad of saving money i am infact loosing some … is that thing true ???

    • Abhishek Jain

      Hi,

      If you are looking for Mitsubishi Electric then there is one 1.5 ton model: MS-GK18VA which is a BEE 5 star rated model. If you are looking for Mitsubishi Heavy Industries then there are 3 models: SRK21CNS-S6 (BEE 5 star), SRK19CK-6 (BEE 3 star) and SRK19CK-6 (BEE 2 star). Mitsubishi is a good brand for sure. As for 5 and 3 star rated AC, the choice will depend on your usage. We typically recommend people to go for BEE 3 star split AC if usage is less than 1000 hrs per year and price of electricity less than Rs 5 a unit. If usage is between 1000-1500 hrs per year, then we suggest going for BEE 5 star split and beyond that Inverter Tech split AC. This is for 3 years payback for the extra money you pay to buy the appliance.

    • ravi

      well i checked in the market and there is mistubushi electric acs model avlaible …. mistubushi heavy elctric model not there … in mistubushi electric also there is 1 3 star model MS-HK18VA …. so how abt this model and will mistubushi be better than lg in 1.5 tons considering cooling, power consumption and after sales service as i saw list prepared by u for the tonnage catagory in which u listed the top model but i dint find mistubushi there in 3 star catagory and top slots were taken by lg if not wrong … bit confused which among these 2 i should prefer if i were u …..

    • ravi

      among mistubushi heavy industries and mistubushi electric i found abt heavy industries review on net that its cooling is great or even better than most premium brands like hitachi , diakin , lg etc but service not as good bz they r just imported by 3rd party but for mistubushi electric i cant find enough on net abt its cooling …. but from net reviews can tell that their service setup is fine . even in my areaa i found thta there is support for mistubushi electric but no service facility for mistubushi heavy industries .. can u tell from ur experience or if u know some person using mistubushi electric , how is their cooling ….. regards

      Hi Ravi,

      Cooling depends on cooling capacity of AC. Higher the cooling capacity, faster is the cooling (or higher the tonnage, faster the cooling). So cooling is specific to model and not to brand. Brand is more for reliability, technology and service.

    • Abhishek Jain

      Also as per my knowledge, ME is as good as other Japanese brands like Hitachi & Daikin in terms of technology and reliability.

    • ravi

      well they r sister company mistubushi electric and mistubushi heavy industries …. but i saw on consumer complaint forum and there people commented on heavy electric .. the major problem they had was with their service bz their products are just imported by international aircon to india and so they dont have great service setup here … but with mistubushi electric i am not able to get any reliable input abt their reliability and service …. so if u have any proper input abt it or know someone using them then let me know the inputs ……

      and thanks for the help i m getting on ur forum . quite informative …

    • Abhishek Jain

      Hi Ravi,

      Sorry we do not have feedback on MHI vs ME comparison.

    • ravi

      finally i have decided to go with mistibushi heavy industries 1.5 tn ac . abhishek have u got any input how far i can rely on their sercive bz i conpared their technology and cooling and area it can cover , its by far more better than mistibushi elctric and lg products … so any intel on their after sales service pls enlighten me with the info ….

    • Abhishek Jain

      The energy efficiency numbers do not look very exciting. Cooling Capacity is 5145 W and power consumption is 1704 watts (http://www.homeshop18.com/ifb-split-1-5-air-conditioner-iacs18ck3tcc-3-star-children-series/household-appliances/home-appliances/product:30548471/cid:4259/) …. which means EER is just about 3.02 … which is quite low. You can certainly get better ACs.

  • Tanushree Sharma

    Hi,Abhishek your website is a great effort! And for my power requirement, I’ve a fridge of 500 watt, a ceiling fan, a CFL, a normal TV.. Would 2kw power supply be enough for 0.8 ton A.C.?

    • Abhishek Jain

      The AC you mentioned has power rating of 910 Watts. Even if we take 1 kW, then you have another 1 kW. Fridge is 500 watts, Ceiling fan would be 75-90 Watts. CFL another 25 watts. A CRT TV would be another 120 watts. So 2 KW should be good enough.

  • Tanushree Sharma

    I have a power connection of 2KW. Would it be sufficient for a 0.8 ton window A/C? What kind of Voltage stabilizer do i need? I have a 100sq.ft room & I’m thinking to buy Haier 0.8 Ton 1 Star HW-09CH1N Window Air Conditioner, and Voltech Voltage Stabilizer (V-Star1). I need an expert opinion. Please help!

    • Abhishek Jain

      0.8 ton window AC should work on 2 kW connection however it will also depend on other appliances that you have (because the sum total of all should be less than 2 kW). Before buying stabilizer you should know the levels to which voltage in your house drops. If it is less then you can go for small range voltage stabilizer, else you would have to go for a larger voltage range stabilizer. Some companies make stabilizers only for ACs which have intelligent time delay system which protects compressors. So it will be better to go for such voltage stabilizer. The model you have chosen seems to be good for ACs.

  • Satish Shah

    Hi Abhishek,

    Please suggest some good AC brands for room size 13×11 foot, height 11.5 feet, which consumes less electricity & cools effectively. I intend to buy 1.5 ton split AC. There are 4 windows in the room. It is in ground floor and there is no direct sunlight on AC. Our usage would be around 800-900 hrs annually.
    Also please suggest the machine position of indoor and outdoor unit. Should the outdoor unit be at the same level(height) or more as the indoor one?

    Thanks!

    • Abhishek Jain

      Which city is this for? Do you get direct sunlight on the ceiling or any of the walls of the room?

  • Parool

    Hi Abhishek,

    I wanted to know, that what is the performance meter for Hitachi air conditioners in India?
    How about the services from them? Coz I can see a lot of bad reviews on net for Hitachi.

    On the other hand my mind was set on Hitachi AC’s coz of the difference in EER ratios.
    On comparing it to any other brands which states the EER as no more than the range from 3 to 5, Hitachi states it as 10 and above. So the difference is a lot.

    Hence, shall I go for Hitachi or not?

    • Abhishek Jain

      Hi Parool,

      Hitachi certainly has the highest EERs but it is wrong to compare the numbers that show in range of 10 to those in between 3 and 5. Energy Efficiency of Air conditioners is mentioned in EER as well as COP and they are used so interchangeably that it gets confusing at times. Unit for COP is Watts/Watts (or W/W) and this value typically ranges between 2 and 4 for all ACs in India. EER is in BTU/Watt.hr and it is 3.41 times COP value and ranges between 6.82 and 13.64 for all ACs in India. Whenever you are comparing 2 ACs and for one you see a value between 2 and 4, and for other you see a value between 7 and 13, simply divide the bigger value by 3.41 or multiply the smaller value by 3.41.

      Now we have also heard complaints about Hitachi service but we have also seen people specifically asking for Hitachi. So it is kind of mixed response. Hitachi as a brand is known for their quality, however we have heard complaints about their higher noise levels too. Some people had good experience with Hitachi and want to purchase it again, while some complain. So if you do not have any personal experience with the brand or not know someone in your area who has had good experience with the brand, then going for other brands would be safer. However if you know some people in your area who had good experience with the brand, you can certainly go for hitachi. Because if their service in your area is good, it can work very well.

    • Parool

      Thanks Abhishek for the reply.

      This blog seems really informative and hence helps a lot in taking an informed decision.

      Well, with your suggestion, I have asked a few people nearby who said “nothing like Hitachi. Go ahead.”
      So i guess I will go for it then.

      Any suggestions for the stabiliser? the voltage fluctuation at this place is very high. At few times, it is said to be around 90, i heard. So, what brand and what type of stabilizer would you suggest and what would be the price range?

    • Abhishek Jain

      Hi Parool,

      I am glad that you were able to decide and found the website useful. 90V is too low a voltage and if it really goes that low, you should complain about it to your utility. It will be hard for any stabilizer to step up the voltage from 90V to the desired voltage level. One brand that I have used and which has very big input voltage range is Blue Bird (http://www.bluebirdstabilizer.com/voltage_stabilizer.html). It has specs to handle 115-270 V input. But even the output is 195-245 which means at 115 V input it will scale it up to 195V output. There are some voltage stabilizers that can handle 90V input. Some of them are there on these links:

      http://www.snapdeal.com/product/staar-automatic-voltage-stabilizer-90/1353189
      http://www.stylexindia.com/prod_stab_mainline.htm
      http://www.bpower.in/main-line-voltage-stabilizer.htm
      http://www.desta.in/automatic-voltage-stabilizers.htm

      But I am not sure about the quality of these stabilizers. They may be good but I have no experience with them to vouch for their quality.

    • ravi

      very true what abhishek told u … i have purchased ac from one of my relatives shop and even he said that their service is a problem last couple of years ….he told me to go for o general if i can afford it but its very sensitive to fluctuations thats only thing due to which some cases of problem arised with his customers … second was mistibushi heavy industries as their serivces are getting better and that only thing it was lacking its in mid range but the copper wire cost will be additional bz none imported sets provided with copper wire and third is lg to fit the pocket and if u are basically looking for service they r the best .. hoped i helped with ur question thats the data i did confirmed with some others too b4 purchasing hope it helps others too …..

    But it consume 8.9 amp. One hour use consume 1.5unit. Is it ok or proble in machine.
    Also gril temp. Is13.5. Pls guide me isit ok . Ac is only 10days old.

    • Abhishek Jain

      What temperature are you keeping the AC at? Is there direct sunlight on the AC? Are you getting low voltage in your area?

    • visahl mehta

      i keeping ac in 26c. no direct sunlight on ac. … voltage 220 to 240 ..

    • Abhishek Jain

      You should complain this to LG as instead of 1610 watts, at 8.9 amp it is taking almost 1920 watts. In fact this should also go to BEE so that it’s star rating is re-validated.

    • Abhishek Jain

      Can you give me your model number?

    • visahl mehta

      my model no. lg LWA5CS3F

    • Abhishek Jain

      Thanks. Do register a complain with LG.

    • visahl mehta

      lg told me 1 amp. ka variation rahega. aur vo log hero honda ki avrage ka example dete he.
      my voltage is 220 to 240.
      what can i do. sir pls guide me.

      amp. 8 consuption to raheta hi he.

    • Abhishek Jain

      Hi Vishal,

      1 amp variation is variation of 200 watts!! It can change BEE rating by 2 levels!! There is process in BEE to challenge star rating and in fact a few samsung, panasonic and godrej models were stripped of their star rating a few days back. So I guess if it is not possible to return the AC then the solution is to go to BEE and challenge the rating or go to consumer forum.

  • ravi

    hello abhishek,

    I have two rooms connected 12×14 foot and 7.5×12 foot , i want to cool both rooms . what tonnage ac i should go for. i house is in kanpur , it has 2 windows and in noon time direct sun rays come , and i am on the ground floor , I asked for suggestion and some people suggested me to go for lg 2 tonnes and some said if u can go in higher range go for o general as it will cool both room with less load on compressor for 1.5 tonnes ac . i am bit confused which brand will be good so that later on i dont have problem with maintanance, eleectricity or any other problem … kindly suggest which company ac to choose and what tonnage as per my requirement so that electricity is saved and after sales maintainance is less …. and ya also give the suggestion under saame condition if i just have to cool one room of size 12×14 foot instead of 2 rooms.

    regards

    • Abhishek Jain

      When you say ground floor, I assume that there are more floors on top of the room. And also I assumed that you do not have a sun facing west/south west wall. In that case you need about 2.5 tons of cooling if you want to cool both the rooms during peak summer day time. If the usage is only at night then 2 ton would be sufficient for both the rooms combined. 1.5 ton AC would be good if you want to use the AC only for 12×14 room (both during day and night). Smaller the AC lesser is the electricity consumption. And I must say even 1.5 ton O General AC will not be able to cool both the rooms together. You will have to go for 2 ton at least (assuming usage is mostly at night). If you can tell me the tonnage that you want to go for, I can suggest you some models.

    • ravi

      well i want 1.5 tonnes then . later if not satisfied then i will go for 1 tonne ac seperately for the small room . so suggest me which ac i should go which is best as far performance is concered …and after sales maintance and service. bz i was searching for o general review so i saw many people were complaining abt them abt their service and in their indian models there was some problem in their ac though i asked few shopkeepers and they suggested me o general if i can afford the price as its air flow range is best and in low raange they told me lg is good . though i wanna know ur opinion since i am confused which will be the best choices for the above criteria and i cant rely much on online reviews since many sites give negative reviews them selves to gain popularity ….

      regards

    • Abhishek Jain

      O General is a good brand for technology/reliability, however their ACs do not rank high in electricity consumption efficiency. However you can look at these models:

      Hitachi RAU518HUD
      Godrej GSC 18 FG 6 WNG or GSC 18 FG 6 ONG or GSC 18 FG 6 BNG
      Whirlpool 3D Cool Climate Control PLT V or 3D Cool Elite IV
      or any LG BEE 5 star rated model
      Mitsubishi MS-GK18VA

    • ravi

      well i asked some air conditioners shop they said if u goin for o general which is high range better go for mistabushi bz none of the customer who purchased mistabushi had no problem till now and every ac company almost uses mistubushi compressor .. is that truee abt compressor ? and will mistubushi be right choice for 1.5 tonnes as far cost of electricity and after sales service . so far i am considering abt mistubushi, lg, hitachi, and daikin … so give ur opinion … And if their is any draawback in mistubushi or above stated brand let me know so i can compare their pros and cons …..

      regards

    • Abhishek Jain

      Most top Japanese brands have their own compressors. Hitachi, Daikin, Mitsubishi have their own compressors. In fact many local brands just assemble the components purchased from these companies. As japanese companies make their own compressors, the designs are more stable as their components work well with each other. And thus their reliability is high as compared to local brands. However while buying AC you should also look at the efficiency of the compressor. Reliability is one aspect, efficiency is also important. Hitachi, Daikin have models that are extremely good in energy efficiency (at least the EER numbers show that). Mitsubishi also has a few models that rank high in efficiency. So I think you should give equal importance to both the factors and choose the right model (rather than focusing too much on the brand, after you have finalised top few brands).

  • G Samant

    Hi abhishek,
    I shifted to a new house in delhi 4th floor, total floors are 6.
    I have 3 bd rooms all 14×12. A 28×12 living room and a 18×12 dining room.
    I have put blinds on my windows to avoid direct sunlight.
    Can you suggest a MULTI-split ac arrangement for me.
    I intend to use 3 indoor units in each bd room and 2-3 indoor units in my drawing dining as it longer in shape.
    Also any particular brand with good multi split arrangement.

    • Abhishek Jain

      Hi,

      14×12 rooms would need 1.5 tons cooling. 28×12 room would need 3 tons of cooling and 18×12 room would need 2 tons of cooling in Delhi (assuming the walls also do not get much direct heat from sun). You can look at Daikin or Sharp’s multi split inverter AC for your house. You can call their engineers for evaluation.

  • Sandeep

    Hi Abhishek,

    First want to say thanks for running such a useful and informative website and doing a great service towards the good of society.

    Second my question, I am looking for an Windows AC for a room size of 17×14 in Delhi. This room doesn’t really get direct heat from any side and is on first floor of 8 storey building. There is no electrical appliance (excluding Fan and Light obviously) and just one double bed and an Almirah is there in room. And generally there would not be more than 3 person at anytime in the room.

    What would be the best model for AC you would suggest to me?

    Thanks in advance for your answer.

    • Abhishek Jain

      Hi Sandeep,

      I am glad that you found the information useful. For a 17×14 room in Delhi, the tonnage requirement would be about 2 ton (for a non sunny room). You can get 2 ton window ACs, but they would not be energy efficient. Best 2 ton window AC would be rated as BEE 2 star which is equivalent to BEE 1 star split AC. We typically do not recommend people to go for less than BEE 3 star split AC and recommend people to go for BEE 3 star split AC if usage is less than 1000 hrs per year and price of electricity less than Rs 5 a unit. If usage is between 1000-1500 hrs per year, then we suggest going for BEE 5 star split and beyond that Inverter Tech split AC. This is for 3 years payback for the extra money you pay to buy the appliance.

      I would suggest you to reconsider going for Split AC.

      Which city?

  • Rahul

    Hi Abhishek,
    I am Rahul from Kolkata. I have two rooms 11’X11′ and 10’X14′. height(11′) for both. I want to buy an Split AC which have 2 outlets for these two rooms(May be it’s called multiSPLIT). Please suggest me the best energy saving one.

    • Abhishek Jain

      Hi Rahul,

      For room one: You need a 1.2 ton AC if there is no direct sunlight on west/south-west wall and on ceiling, and in general room is less sunny. Else if the west/south-west wall or ceiling get direct sunlight and there is good amount of sunlight from the windows, then you need about 1.5 ton AC. If you need 1.2 ton AC, you can also go for 1 ton inverter AC which will be quite energy saving. However in case of 1.5 ton AC, you will have to go for 1.3 ton inverter AC (of which there are only 2 models in market) or 1.5 ton inverter AC.

      For room 2: You need a 1.3 ton cooling if there is no direct sunlight on west/south-west wall and on ceiling, and in general room is less sunny (you can go for 1.2 ton if usage is mostly at night). Else if the west/south-west wall or ceiling get direct sunlight and there is good amount of sunlight from the windows, then you need about 1.7 ton cooling (or 1.5 ton if usage is mostly at night). If you need 1.3 ton AC, you can also go for 1.3 ton inverter AC which will be quite energy saving. However in case of 1.7 ton AC, you will have to go for 1.5 ton inverter AC.

      We typically recommend people to go for BEE 3 star split AC if usage is less than 1000 hrs per year and price of electricity less than Rs 5 a unit. If usage is between 1000-1500 hrs per year, then we suggest going for BEE 5 star split and beyond that Inverter Tech split AC. This is for 3 years payback for the extra money you pay to buy the appliance.

      Let me know the size and type you need and I can suggest you some good models.

    • Abhishek Jain

      Forgot to add: A multisplit makes sense when you need 3 or more units. For two units, it is better to go for individual units.
